When I was about 3 we lived on a small farm with a pond. I heard this bullfrog at night and didn't know what it was, so I asked my mother. She offhandedly said "It's a bullfrog - that's a great big boy frog that lives in the pond. He's calling out because it's warm."
Although she meant "great big" in comparison to the other (female) frogs I thought she meant in comparison to HERSELF. Therefore I imagined this 7 or 8 foot frog in that bitty pond and wondered why I hadn't seen him, but was too afraid to go look.
A few years later I saw a bullfrog and realized what she meant.
